What is 304 Perforated Sheet?
304 perforated sheet is a type of metal sheet made from high-quality 304 stainless steel, processed through CNC punching machines to create custom-designed holes based on client requirements. The resulting sheet combines structural strength, aesthetic appeal, and functional versatility, making it a popular choice across a wide range of industries such as filtration, ventilation, safety protection, and architectural decoration.
Alternative names include:

Stainless steel punched sheet
Material Introduction: Why Choose 304 Stainless Steel?
304 stainless steel is a widely used austenitic stainless steel grade known for its excellent corrosion resistance, high temperature tolerance, and ease of fabrication. With its balanced composition of chromium and nickel, 304 stainless steel is ideal for punching and shaping into durable and attractive perforated sheets.
Main advantages of 304 stainless steel:
Excellent resistance to corrosion from acids, alkalis, and salts
High thermal resistance
Suitable for outdoor and humid environments
Smooth surface with high aesthetic value
Easy to punch, weld, and form

Variety of Hole Types
304 perforated sheet is available in a wide selection of hole shapes and patterns. Customized layouts—such as straight rows, staggered rows, and circular formations—are designed to meet both functional and decorative requirements.
Common hole types include:
Round holes (ideal for ventilation and filtration)
Slotted holes (good for drainage and airflow)
Square holes (suitable for sieving and decoration)
Triangle holes
Hexagonal holes (honeycomb structure for strength)
Fish scale holes, bridge holes, star holes
Cross holes, nail-shaped holes, pentagon holes
Human-shaped holes, “井” (grid) shaped holes, and other custom patterns
Technical Specifications & Customization
To suit different applications, 304 perforated sheets can be tailored in terms of thickness, hole diameter, and overall size.
Thickness: Customizable from 0.1mm to 20mm
Hole diameter: Precisely made to order
Sheet dimensions: Full sheets or cut-to-size available
Open area: Adjustable to balance airflow and strength

Key Performance Features of 304 Perforated Sheets
304 stainless steel perforated sheets not only offer visual appeal but also deliver outstanding functionality. Their wide range of uses is supported by several key material and structural advantages.
1. High Sand Resistance and Filtration Performance
Multi-layered configurations offer excellent sand-blocking capabilities, ideal for oil and gas wells where sand control is critical.
2. Uniform Hole Distribution and Anti-Clogging
CNC precision punching ensures even hole spacing, enhancing permeability and reducing the risk of blockages.
3. Large Filtration Area, Low Resistance
High open-area percentage ensures large flow capacity with minimal resistance—ideal for filtration and heat dissipation systems.
4. Superior Corrosion Resistance
The inherent properties of 304 stainless steel ensure long-term stability in harsh environments, including exposure to acids, alkalis, and saline media.
5. Structural Stability and Deformation Resistance
Multi-layer welding or composite punching processes reinforce structural integrity, making the sheets resistant to warping or pressure damage.
Broad Range of Applications
Thanks to their performance versatility and customizable design, 304 perforated sheets are used across a wide spectrum of industries and projects.
Common applications include:
Architectural Design: Wall cladding, ceilings, stair railings, facades
Industrial Filtration: Air and liquid filtration systems
Oil & Gas Industry: Sand control screens and filters
Agricultural Equipment: Grain sieving, aeration systems
Environmental Engineering: Wastewater treatment, dust collection units
Transportation Infrastructure: Subway ventilation covers, highway noise barriers
Home Appliances: Speaker grilles, cabinet vents
Conclusion: Why Choose 304 Perforated Sheet?
